Objective: To assess the quality of diabetic care provided in primary health care settings in Oman.Methods: This was a cross-sectional study of randomly selected 500 patients with diabetes mellitus (DM) attending 6 primary care diabetic clinics in the north Al-Batinah region of Oman from January to December 2010. Nine standards on the quality of diabetes care were audited.Results: The mean age of the sample was 51±13 years, ranging from 15 to 87 years; the majority (61%) were females. The mean duration of DM was 4±3 years, ranging from 1 to 18 years. Seventy-seven percent of the patients attended diabetic clinics at least 4 times per year. Of the 9 assessed diabetic standards, HbA1c was documented in 33% of the patients, body mass index in 12%, low-density lipoprotein cholesterol (LDL-C) in 40%, urinary albumin:creatinine ratio in 28%, creatinine in 63% and blood pressure (BP) in 96%. Optimal control among the documented indicators was noted in 32, 21, 25, 85, 95 and 19%, respectively. Twenty percent of the patients had their ECGs done while only 39% of the patients had foot examination. No patient had attained control in all of HbA1c., BP and LDL-C.Conclusion: There is a gap between the recommended DM care guidelines and current practice with consequent poor quality of care in these patients.
